Mike Cameron added a two-run shot in his second game back from the disabled list, and David Wright hit a solo home run for the Mets, who won for the fifth time in six games.

Piazza went 2-for-4, a day after getting four hits in a win over Philadelphia. In two games following a 1-for-21 slump, he has raised his average from .198 to .242.

He hit an 0-1 pitch from Doug Davis (3-4) into the second tier of the left-field seats in the second inning, a drive estimated at 434 feet. After Carlos Beltran's run-scoring double in the third, Piazza hit Davis' first pitch 402 feet to the same tier of seats in left. It was his fifth home run of the season, giving him 35 career multihomer games. His last one had been last June 5 against Florida.

The Brewers scored a run off reliever Heath Bell and had men on first and second with one out in the ninth. With normal closer Braden Looper having pitched the last two days, Roberto Hernandez came in for one out before Dae-Sung Koo walked a batter to load the bases. Looper finally came in and got Carlos Lee to fly to left for his seventh save in nine chances.

Cameron, who was 2-for-4 with two doubles and two runs scored in his season debut Thursday, made it 6-1 with his first homer, a two-run shot to deep center with two outs in the fourth.

Wright connected off reliever Matt Wise in the eighth for his fifth homer.

Cliff Floyd went 0-for-4, snapping his career-high 20-game hitting streak, the longest in the majors this season.

Victor Zambrano (2-3) won for the first time since beating Philadelphia on April 19. The only batter he had trouble with was Lee, who had a run-scoring double in the first and a solo homer leading off the sixth.

Zambrano retired the next two batters after Lee's homer, but Russell Branyan doubled and scored on J.J. Hardy's single that chased Zambrano. Bell took over and struck out pinch-hitter Jeff Cirillo to end the threat.

Zambrano allowed six hits, struck out four and walked four in 5 2-3 innings. He also had two singles for the first two-hit game of his career.

Davis was coming off a five-hitter against Cincinnati, his first complete game since August 2003, but wasn't nearly as sharp against the Mets.

He struggled through six innings, giving up six runs and seven hits. He has lost four of his last five starts.

The Brewers scored first on Lee's two-out double in the first.
